Hi Everybody, I am working in implementing wavelet transform and inverse wavelet transform in C6711 IDK. I read thru the code in TI's manual but could not understand the implementation of the sliding window and double buffering schemes that they use to bring in the data from the External memory to Internal SRAM. They used DMA streams using dstr_open() and dstr_init() for initializing , could someone please explain them conceptually, also i find it difficult to downsample the input image along the columns. Specifically in all examples they use the dstr_get()and dstr_put(). Can i implement my own code to implement the sliding window and if so how can i implement it? Thanks in advance, -Vijay |

I assume you have looked at SPRA636 ? Andrew E.
